Embodiment Construction

[0014] In order to make it easy to understand and understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained in conjunction with specific embodiments below.

[0015] See figure 1 , Which is a cross-sectional view of the hollow wire with reinforcing ribs of the present invention, including the wire wall 1 of the hollow wire and a plurality of reinforcing ribs 2 arranged in the hollow wire. The reinforcing ribs 2 are arranged in the axial direction of the wire and surround the wire wall 1 The hollow cavity formed is divided into a plurality of water flow channels 3. The reinforcing rib 2 plays a supporting role for the hollow wire, so that the middle of the hollow wire does not dent inward when the coil is wound, so as to ensure the cross-sectional area of ​​the water flow channel and ensure the heat dissipation effect.

[0016] The aforementioned wire material can be aluminum, copper o...

Abstract

The invention relates to a hollow conductor with reinforcing ribs for a water-cooled transformer and a water-cooled electric reactor. The conductor comprises a conductor wall and at least one reinforcing rib arranged in the conductor wall, and a hollow cavity defined by the conductor wall is divided into a plurality of flow water channels by the reinforcing ribs. The hollow conductor with the reinforcing ribs can effectively avoid the phenomenon that the sections of the hollow-out channels are reduced due to inwards recessing of the hollow conductor caused by bending deformation in the process that the hollow conductor is wound into a coil, and ensure the sectional area of the water flow channels and the cooling effect of the water-cooled transformer and the water-cooled electric reactor.

Description

Technical field [0001] The invention relates to a hollow wire, in particular to a hollow aluminum wire and a hollow copper wire with reinforcing ribs. Background technique [0002] Traditional reactors and transformers can be divided into hollow type (reactor), iron core type, dry type, oil intrusion type, etc. according to the structure. The cooling methods of the above reactors or transformers are natural cooling, and the passing current is small. When the side current reaches thousands of amperes, the required wire cross-section requirements are relatively large. [0003] For this reason, water-cooled reactors came into being. The water-cooled reactors are divided into tubular water-cooled reactors and plate-type water-cooled reactors. Tubular water-cooled reactors are mostly used in wind power converters, photovoltaic inverters and in smelting and induction heating. And other industrial equipment. [0004] However, the current tubular water-cooled reactors and transformers gene...
